having a spine over the base of the telson, while T. neglecta possesses 

 one. It may also be remarked that the genus Thysanoessa need not 

 be confounded with Boreophausia if the slightest attention is paid to 

 difference in the form of the eyes and the length of the first pair of 

 legs. Boreophausia inermis has been recorded from the Clyde and 

 the Moray Firth, and also from Shetland ; while Thysanoessa lon^i- 

 caudata has been recorded from St. Andrews Bay. T. SCOTT, Leith. 



On the occurrence of Rhynchomyzon purpuroeinetum (Th. 

 Scott} in the Moray Firth. - - This well-marked Copepod was 

 dredged by Mr. F. G. Pearcey in the Moray Firth in November 

 1897 at two widely different localities, viz. off Nairn and in the 

 vicinity of Smith Bank. The thorax in this species is narrowly ovate, 

 and the abdomen is elongate and slender ; the last three thoracic 

 segments are of a dark purple colour. The species was described 

 in 1893, in Part III. of the "Eleventh Annual Report for Scotland," 

 from specimens obtained in the Firth of Forth. It was described 

 under the name of Cyclopicera purpurocinda, but Dr. Giesbrecht, in 

 his revision of the Ascomyzonticke, to which it belongs, removed it to 

 a new genus as above. Though Rhynchomyzon purpuroeinetum has 

 been found in only a few places in the British seas, it appears to 

 have a wide distribution, seeing that Dr. Giesbrecht has recorded it 

 from Naples. It does not appear to be a littoral species, but seems 

 to live at a moderate depth in the open sea. T. SCOTT, Leith. 



Thalestris hiberniea, G. S. Brady, in the Cromarty Firth. 



This was one of a number of interesting Copepoda that were dredged 

 near Invergordon in October 1896. It is one of the rarer species 

 of British Thalestris. In the " Monograph of British Copepoda" by 

 Professor G. S. Brady, Thalestris hiberniea is recorded from West- 

 port Bay, Ireland, and from the Clyde and Oban, Scotland ; 

 Cromarty Firth appears to be a new station for it. The form of 

 the " hand " of the posterior foot-jaws is quite characteristic of this 

 species when taken along with the fifth pair of feet in the male and 

 female ; it may also be distinguished by the student of this group of 

 Crustacea by its peculiar " habitus " appearance. T. SCOTT, Leith.
